STONE WASHER AND DRIER.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application led January 15, 1914. Serial No. 812,304.

To all whom t may concern Be it known that I, WILLIAM LANGE, a citizen of the United States of America, and a resident of Tomkins Cove, in the county of Rockland and State of New York, have invented certain new and useful Improve` ments in Stone Vashers and Driers, fof which the following is a description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to stone washers and driers of the horizontal axis, rotating drum type, for washing and drying broken or crushed stone and the like, and my inven tion consists in providing an improved machine of the above type, which will receive unclean broken or crushed stone and the like, together with impurities and water, from a suitable conveyer, through an orifice in one end of the drum of the machine, into one compartment where it may be thoroughly washed, pass it to a second compartment where it may be again washed or rinsed and partly dried, and pass it to a third compartment where the drying process is continued and concluded, the dirt and water being returned from the second and third compartments to the first compartment and the dried broken or crushed stone and the like being delivered through an orifice in the opposite end of the drum.

Suitable means for supporting and rotating the drum is provided and suitable means for feeding and emptying the drum is also provided but the supporting and rotating means and the feeding means may be varied in construction without affecting the operation of the drum or the action of and on its contents, the constructions shown being convenient but not indispensable.

In the drawings-Figure 1 is a front end elevation of a stone washer and drier embodying my improved construction; Fig. 2 is a right hand side View of the same; Fig. 3 is a top plan view of the same; Fig. 4 is a vertical section through the upper portion of the rotating drum on a larger scale than the preceding figures; Fig. 5 is a detail vertical section on the line 5-5 of Fig. 4; Fig. 6 is a detail vertical section of a portion of the upper part of the rotating drum showing a portion of the partition between the first and second compartments; Fig. 7 is a detail vertical section of a portion of the upper part of the rotating drum showing a portion of the partition between the second and third compartments; Fig. 8 is a detail.

section of a modified form of screening tray designed to advance the material; Fig. 9 is a diagrammatic view showing a modification comprising an inclined drum designed to advance the material and Fig. 10 is a detail vertical section on the line 10-10 of Fig. 41.

On a supporting frame comprising the I- beams l1, the Lbeams 12, the short I-beams 13, and the diagonal braces 11i, are mounted the plates 15, 16, 17 and 18, supporting the pairs of bearings 19, 20, 21 and 22, carrying the parallel shafts 23 and 241, and also a block 25 supporting the base plate 26 of a motor 27, which motor 27 operates a shaft 28 on which is mounted a gear 29 meshing with a gear 30 mounted on the short shaft 31, which is mounted in bearings 32, the shaft 31 also carrying a gear 33 meshing with a gear 3ft mounted on the shaft 23, motion being communicated from gear 31 through the shaft 23, a gear 35, a chain 36, and a gear 37, to the shaft 24k. By this arrangement the motor27 causes therotation of the two parallel shafts 23 and 24C both in the same direction and at the same speed. By means of bearing pulleys 38 secured at intermediate points on the shafts 23 and 24 motion is communicated to the drum 39, the drum being guided in its movement by the flanges 40 of each of the bearing pulleys.

The above described supporting and driving means, although designed by me for use with the present and similar rotating drums, forms no part of the present invention, which relates more particularly to the construction of the rotating drum and its inclosed parts, so that it is within the scope of my invention to use any rotating means in connection with the rotating washing and drying drum and its inclosed parts, and also to feed it with any convenient style of feeding device, and to remove the contents with any convenient style of removing or delivery device.

The rotating washing and drying drum 39 has an inner head which comprises a circular rear integral face plate part 1il and rear end ring part 44, the face plate part t1 being provided with water escape holes 42 and a central inlet orifice 43, and the ring part 14 being turned at right ano'les to the face plate part 4l so as to encircle the rear end of the shell of the rotating drum, which also has an outer head which comprises a circular front integral face plate part 45 and front end ring part 47, the face plate.

part 45 being imperforate except for attaching means and a central outlet orifice 46 of smaller diameter' than the inlet orifice 43, and the ring part 47 being turned at right angles to the face plate part 45, so as to Vencircle the front end of the shell of the rotating drum. rl"he rotating washing and drying drum 89 also comprises two intermediate combined integral partitions 48 and 52 and rings 5l and 55, the partition part 4 8 of the rear intermediate combined integral partition and ring being provided with water escape openings 49 and an orifice 50 yof no larger diameter than the inlet orifice 48, and the ring part 51 extending at right angles to the partition part in both directions, so as to encircle the shell of the rotating drum at an intermediate point. rIhe partition part 52 of the forward intermediate combined integral partition and ring is provided with water escape openings 58 and an orifice 54 of smaller diameter than the orifices 43 and 50, and the ring part 55 extends at right angles tothe partition part 52 in both directions, so as to encircle the shell ofthe rotating drum at an intermediate point.

The shell of the rotating drum 89 comprises a rear cylindrical section 5G secured between the rear end face plate part 4l and the rear intermediate partition part 48 and secured to the rear end ring part 44 and the rear intermediate ring part 51 and provided with a circular series of closely arranged wearing lining sections 57 (see Figs. 1 and 10) formed with perforated screening trays 58 which are radially arranged at approximately right angles to the lining sections 57 so as to provide in connection with the lining sections 57, the trough shaped material receiiffing pockets of approximately rectangular shape in cross section.V The shellof the rotating drum 39 also comprises an intermediate cylindrical section 59 secured between the rear intermediate partition part 48 and the forward intermediate partition part and secured to the rea'r intermediate ring part 51 and the forward intermediate ring part 55 and provided with rearwardly impelling spiral blades 60. The shell ofthe rotating drum 89 also comprises a front cylindrical section 6l secured between the forward intermediate partition part 52 and the front face plate part 45 and secured to the forward intermediate ring part 55 and the front ring part 47 and provided with rearwardly impelling spiral blades 62.

Each ring and section of the drum is made preferably in siX'pa-rts, suitably bolted or riveted. together, although any convenient number of parts may be used or they may each be one integral part, all of .which being constructive details depending on' the size of the drum and the material used may be considered for the present as of minor importance.

The end rings are thickened and beveled as at (S3 so as to fit the guiding flanges 40 of the bearing pulleys 38, this construction allowing for considerable wear without impair-ing the efficiency of the contact between the rings and the bearing pulleys.

Wearing linings 64l and 65 are secured t0 the rear face plate part41 and the rear intermediate partition part 48 respectively, and are of such construction as to form in connection with said parts annular spaces 65 and 67. The lining 65 is provided with numerous water escape .holes 68.

Spaced wearing linings 69 and 70 are secured to the rear intermediate partition part 48 andl the forward intermediate partition part52 respectively and carry bearings 71 and 72 in which are mounted a circular series ofhollow rods 73 which form an inner and replaceable shell and screen. Holes 74 are provided inthe wearing lining 69 for 'access to the fastening means of the rear intermediate partition plate 48. The space wearing linings 69 and 70 are further pro vided with mountings for non-radial (see Fig. 1,) screening trays and form in connection with the parts to which they are secured the spaces 76 and 77 which serve as side drains for Ythe escape of water. The annular space 78 between the rods 78 and the shell of the drumk serves also as a drain to carry the escaping water to the first compartment. i Y

Spaced wearing linings 7 9 and 80 are secured to the forward intermediate partition part 52and front face plate part 45, formV ing spaces 81 and 82 for the escape of water and carrying mountings for double faced non-radial (see Figs, 5 and 8) screening trays 83, and a circular series of hollow rods 84, the latter forming as in the case'of the series ofl hollow rods 73 a replaceable shell and Ascreen for carrying material to be screened andmdried. An annular space 85 betweenthe series ofhollow rods 84 and the shell of the drum serves as a drain for water collected from this compartment and to carry it to the second compartment. The diameter of the circular series of hollow rods 84 is somewhat less than that of the circular series. of hollow rods 73 so that there may be plenty of space between them and the shell of the drum to avoid the danger of flooding thembya backing up of the water. Holes 86' and 87 permit'the draining of water from the trays to the side spaces 81 Eachdouble facedscreening tray 83 comprises a-front .perforated plate ror face v88 and a back imperforate lplateor face .8 9

edges nearest the-i airis ofthe drum and open at their' edges farthest from the axis of the drum and also at their ends, thus providing an intermediate space 90 between them for the escape of water from the front perforated face to the side spaces S1 and 82 and the drainage space 85, without permitting the water to drop onto the next following tray. lt is obvious that water may also escape through the spaces between the individual rods of each series of hollow rods to the adjacent drainage space, and that water collecting in the intermediate space 90 during the upper half of the travel of each double faced screen S3 may, owing to the shape of the edge 91 of each screen and the proximity of the holes SG and 87 to this edge, be conducted to the side spaces 8l and 82 when the angle of the screen will not permit the escape of water to the spaces between the hollow rods.

In operation the uncleaned material, comprising` broken or crushed stone, dirt, sand, and other foreign substances and water, is admitted through the inlet orifice 43, carried around on the screening trays 58 and washed, passed through orifice 50 to the screening trays and circular series of rods 73 and rinsed, passed through the orifice 5ft to the screening trays 83 and the circular series of rods S4 and dried, and then passed out through the front orifice 4G.

The water, sand and other line material passes from the screens in the third cornpartment to the side passes and drainage space and is impelled to the second compartment by the impelling blades G2. ln the second compartment it joins with the water, sand and other fine material for use in rinsing and is impelled by the impelling blades 60 to the first compartment where it joins the water, sand and other fine material in that compartment and when there is an excess of such material lit may escape through the holes 41:2 to a sewer or other place of disposal.

The conveyance of material from the feeding means to the first compartment, from the first compartment to the second compartment, from the second compartlnent to the third compartment, and from the third compartment to a point without the drum, may be secured either with the use of well known transferring chutes which catch material dropped from the upper part of one compartment and transfer to a lower point in the succeeding compartment as shown in Figs. 1, 2 and 3; the transferring position being shown in full lines and the idle position being shown in dotted lines in Figs. 1 and Q, or with the equally well-known tilting of the rotating drum produced for in stance by an inclined support as shown in Fig. 9, or by giving the individual screening trays a slight deflection so that they will act as slow rotary conveyers as shown somewhat exaggerated in Fig. 8. In the present instance the drawings are constructed from a machine which makes approximately two revolutions per vminute and has about thirtysix screening trays in each circular series, and the deflection of these trays although very slight is sullicient to transfer the material with sullicient rapidity taking into consideration the amount of cleaning necessary.

To produce an inclined support as shown in Fig. 9 it is only necessary to replace the similar I-beams ll` by dissimilar I-beams of varying heights such as Lbeams 92, 93, 94: and 9.3, the inclination required being so slight as not to disturb the equilibrium of the drum and operating apliaratus.

'Io produce a conreying means such as shown in Figs. 1,2 and ll, several spaced parallel bars 9G, supporting pivoted chutes 97 in single or multiple series, are passed through the drum and suitably supported without the drum, the pivoted chutes 97 being moved into and out of operative position by means of crank arms 9S and rods 99, transference of one grade of material beingelfected by means of one series of chutes and transference of another grade of material being effected by mcansof the other-series of chutesin the case where more than one series of chutes is employed or transference of all material being effected by use of all the chutes, as desired, the material being ultimately delivered to the chutes 2100.
